228 NEW SPECIES MELYRIDAE, CHRYSOMELIDAE AND TENEBRIONIDAE 



tate, punctures rounded, scarcely coalescent. Antennae moderately short 

 and somewhat stout, reaching a little beyond the base of the pronotum. 



Pronotum nearly as long as wide, not noticeably transverse, appar- 

 ently widest at the middle ; sides rather moderately arcuate, finely beaded ; 

 apex and base subtruncate, not strongly beaded; apex a little narrower 

 than base; apical angles subrectangular ; basal angles obtuse and some- 

 what rounded ; disk moderately strongly convex from side to side, quite 

 narrowly explanate and impressed within the bead; punctate, punctures 

 more or less irregularly placed, moderately coarse, partly somewhat 

 slightly elongate at the sides. 



Elytra oval, about three-sixths longer than wide ; sides evenly arcuate 

 and subparallel, obtusely rounded at apex; base truncate, humeri small 

 and slightly prominent anteriorly and distinct; disk rather evenly convex, 

 striae of small punctures which are slightly irregularly spaced and feebly 

 impressed; intervals sometimes slightly convex, finely and sparsely punc- 

 tulate, not tuberculate nor rugulose on the apical declivity. 



Propleura finely and more or less irregularly longitudinally rugulose. 



Abdomen somewhat rugulose and rather more thickly punctate on the 

 first two than on the succeeding segments. 



Tarsi clothed beneath with rather soft yellow hairs. 



Male. Rather narrower, antennae slightly stouter. 



Female. Somewhat broader, antennae somewhat more slender. 



Measurements.-. Female holotype : Length, 5.8 mm. ; width, 2.2 mm. 



The accompanying male allotype measures 7.5 mm. in length ; the 

 elytra are separated and the wings are rudimentary. 



The types are in my own collection. Collected by Mr. W. M. Mann, 

 on May 15, 1904. About twenty specimens in various collections have 

 been studied. 



Type locality. Wawawai, State of Washington. 



Regulus was first referred to pernitens Lee. with considerable doubt. 

 It at first sight resembles aereus Germ, in general facies, from which it 

 differs in the narrower elytra and different punctuation of the head and 

 pronotum. In pernitens the pronotum is distinctly transverse, antennae 

 longer and more slender, elytra broader, sides of the pronotum distinctly 

 explanate with margin reflexed. In both species the mentum is longi- 

 tudinally carinate at middle with the sides opaque, carina smooth and 

 shining. In regulus the pronotum is rather more punctate than rugulose, 

 the reverse in pernitens. The propleura in aereus is sculptured with 

 rather regular, strong, parallel, longitudinal rugae, some of which divide. 



Helops obtusangula, new species. Form elongate ovate, subparallel, 

 moderately depressed. Color brownish to piceous, not metallic ; legs and 

 under surface more or less rufo-piceous. Apterous.
